-3x-y = -17
-x+y=-1
Using addition
-4x +0y = -16
-4x=-16
x=4
Then plug the value of x into one of the original equations
-x+y=-7
-(4)+y=-7
y=-7+4
y=-3
The solution is x=4 and y=-3
Thus (4,-3)

The true statements are:
A. Tree A's heights are less spread out than tree B's heights and
B. Tree A has lower average height than tree B
Explanation:
Standard deviation in this case represents the spreading out of heights of the trees, Since tree A has lesser standard deviation given equal to 5 , it is less spread out than B given equal to 12, hence option A. is true.
The average of a quantity is given by mean so, the average height can be compared by the given mean values of the trees. Since, A has lesser mean value (= 25) than B(=60), tree A is said to have lower average height than tree B hence option B. is true.
14 is closer to 15 because it is only 1 number away
11 is closer to 10 because it is one number away from 10
18 is closer to 20 because it is two numbers away
16 is closer to 15 because it is one number away
Step-by-step explanation:
